WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 246,803, datedSeptember 6, 1881.

Application filed May 10, 1881.

To all whom it may concern:

Be it known that I, JOHN MURRAY, of Woodman, in the county of Grant andState of Wisconsin, have invented a new Improvement in Wash-Boilers, ofwhich the following is a full, clear, and exact description.

My invention relates to that class of washboilers which have theirbottoms sunken or formed into a pit; and it consists of a removableplate adapted to fit over the mouth of the depression or tit in thebottom of the boiler, and provided with a pipe-seat and pipe at one end,holes for the passage of water at its 0pposite end, and a partition orframe having openings and valves, and resting on the bottom of the pit,which frame serves the threefold purpose of a valveseat, a brace tosupport the plate, and a means for preventing lateral movement of theplate, as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a plan interior view of myimproved boiler. Fig. 2 is a longitudinal vertical section of the same;and Fig. 3 is a detail section taken on the line m a: ofFig. 2, showingthe valves.

Similar letters of reference indicate corresponding parts.

The plate a, which is preferably made of tin, is removable and of suchsize as to entirely cover the mouth of the depression or pit d of theboiler A, and is formed with the perforations 0 at one end and with thepipe-seat c at the other end, upon which the bent pipe B fits. This pipeshould be of such length as to reach only a short distance above thewater in the boiler, and I propose to provide interchangeable long andshort pipes for different-sized washings. The pipes are made tapering,as shown, to increase the force of the discharge ofthe stream. Beforethe water becomes thoroughly heated in the boiler the flow through thepipe will be intermittent, which action is due to counter or backwardcurrents produced in the heating-chamber. To prevent thesecounter-currents, and to cause a continuous stream to flow out the pipe,I provide the chamber with the flap-valves it, which open toward thepipe-seat and close when the currents are The (Model) valves are hingedto the valve-frame t, which is secured to the under side of the plate a,and preferably in an inclined position, as shown in the drawings, thoughthis is not necessary.

It will be seen that in my construction the partition or frame t" rests,when the plate a is inserted over the mouth of the pit, on the bottom ofthe pit and extends transversely across said pit, so that said framethus serves the threefold purpose of a seat for the valves, a brace tosupport the plate a, subjected to the weight of the clothes and waterresting upon it, and a means to prevent lateral movement of the plates.

I am aware that a wash-boiler has heretofore been constructed in which aplate provided with a bent pipe at one end and awatertrap at itsopposite end has been secured to the bottom of the boiler over the pit;out in this construction the plate is permanently secured to the boiler,while in my construction it is not, and there is no frame serving thethreefold purpose, as in my construction.

I am awarethat the general principles of my invention are not broadlynew, the same being shown in Letters Patent Nos. 145,558, 128,097, and138,285, and I therefore only claim my peculiar construction, as shownand described.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent, is-

The combination, with a wash-boiler having a pit, d, of the plate a,having perforations c at one end and a pipeseat, e, and pipe B at itsopposite end, and a downwardly-projecting frame or partition, 41,secured to the under face of the plate, and resting on the bottom andextending the full width of said pit, and provided with hinged valves 1'and valve-openings, whereby the plate a is braced against the weight ofthe clothes, stayed against displace ment, and a nearly unobstructedlevel surface is presented to the clothes, substantially as described.
